Insights

Syncytial variant (SV) Hodgkin lymphoma (HL) in children, though rare, indicates a poor prognosis. This aggressive form of pediatric HL requires intensive treatment, and its histology may predict outcomes.

Area of Science:

  • Pediatric Oncology
  • Hematology
  • Pathology

Background:

  • Nodular sclerosing Hodgkin lymphoma (HL) typically has an excellent prognosis in children.
  • The syncytial variant (SV) of HL in adults is associated with a worse outcome.
  • Limited data exists on the syncytial variant of HL in pediatric populations.

Purpose of the Study:

  • To report the clinical features and disease course of three children with refractory syncytial variant Hodgkin lymphoma.
  • To evaluate the syncytial variant as a potential prognostic factor in pediatric HL.

Main Methods:

  • Retrospective multi-institutional study.
  • Analysis of 51 children diagnosed with refractory or recurrent HL between 1997 and 2014 in Israel.
  • Detailed review of three pediatric cases with syncytial variant HL histology.

Main Results:

  • All three pediatric patients with SV-HL experienced multiple, rapid recurrences.
  • Intensive treatment regimens were utilized, including multiple chemotherapy combinations, autologous and allogeneic bone marrow transplantation, and immunotherapy.
  • Outcomes varied: one patient died of disease, one achieved complete response but developed a secondary malignancy, and one remains alive with no evidence of disease.

Conclusions:

  • Syncytial variant histology may represent a poor prognostic factor in children diagnosed with Hodgkin lymphoma.
  • Further research is warranted to understand the specific behavior and optimal management of SV-HL in pediatric patients.

Histone Variants at the Centromere

Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Transcription Elongation Factors

Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...
